Flask vs Starlette: What are the differences?

In web development, Flask and Starlette are both popular web frameworks used in Python. While both frameworks serve a similar purpose, they do have key differences that set them apart from each other.

1. **Asynchronous Support**: Starlette has built-in support for asynchronous operations using Python's async/await syntax, making it more suitable for high-performance asynchronous applications compared to Flask.
2. **Routing System**: Flask uses a traditional route decorator system, whereas Starlette utilizes a more flexible routing system that allows for more complex route configurations.
3. **Middleware Support**: Starlette provides a middleware system that allows developers to easily add additional functionality to applications, whereas Flask requires more manual configuration for middleware.
4. **Deployment Options**: Flask is typically deployed using traditional WSGI servers, while Starlette supports ASGI servers, which are more modern and optimized for asynchronous applications.
5. **Framework Size**: Starlette is a smaller and lighter framework compared to Flask, making it more suitable for lightweight applications where simplicity and performance are key factors.
6. **Community and Ecosystem**: Flask has a larger and more established community with a wide range of plugins and extensions available, while Starlette, being newer, has a smaller ecosystem but is rapidly growing.

In Summary, the key differences between Flask and Starlette lie in their support for asynchronous operations, routing systems, middleware support, deployment options, framework size, and community ecosystems.

What are some alternatives to Flask, Starlette?

ExpressJS

ExpressJS

Express is a minimal and flexible node.js web application framework, providing a robust set of features for building single and multi-page, and hybrid web applications.

Django REST framework

Django REST framework

It is a powerful and flexible toolkit that makes it easy to build Web APIs.

Sails.js

Sails.js

Sails is designed to mimic the MVC pattern of frameworks like Ruby on Rails, but with support for the requirements of modern apps: data-driven APIs with scalable, service-oriented architecture.

Sinatra

Sinatra

Sinatra is a DSL for quickly creating web applications in Ruby with minimal effort.

Lumen

Lumen

Laravel Lumen is a stunningly fast PHP micro-framework for building web applications with expressive, elegant syntax. We believe development must be an enjoyable, creative experience to be truly fulfilling. Lumen attempts to take the pain out of development by easing common tasks used in the majority of web projects, such as routing, database abstraction, queueing, and caching.

Slim

Slim

Slim is easy to use for both beginners and professionals. Slim favors cleanliness over terseness and common cases over edge cases. Its interface is simple, intuitive, and extensively documented — both online and in the code itself.

Fastify

Fastify

Fastify is a web framework highly focused on speed and low overhead. It is inspired from Hapi and Express and as far as we know, it is one of the fastest web frameworks in town. Use Fastify can increase your throughput up to 100%.

Falcon

Falcon

Falcon is a minimalist WSGI library for building speedy web APIs and app backends. We like to think of Falcon as the Dieter Rams of web frameworks.

hapi

hapi

hapi is a simple to use configuration-centric framework with built-in support for input validation, caching, authentication, and other essential facilities for building web applications and services.

TypeORM

TypeORM

It supports both Active Record and Data Mapper patterns, unlike all other JavaScript ORMs currently in existence, which means you can write high quality, loosely coupled, scalable, maintainable applications the most productive way.
